REV 1.1 Page 1 of 3 Copyright © 2016 Fairview Microwave’s SD3457 is an inner DC block with TNC connectors. It has a blocking capacitor on the inner conductor and operates from 10 MHz to 18 GHz. Our TNC DC block offers good insertion loss of 0.75 dB and has a maximum operating voltage of 200 Vdc. DC blocks are commonly used to filter out unwanted DC signals, while allowing AC drive signals to pass through. They can help improve signal to noise ratio (SNR), eliminate ground loops, or provide isolation in your test setup. All of Fairview Microwave’s DC blocks are in stock and available to ship same-day.
